Specification of Letters Patent.

Patented July 14, 1914.

Application filed January 9, 1911. Serial No. 601,600.

To all whom it may concern Be it known that I, KARL KIEFER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented anew and useful Improvement in Closures for Containers, of which the following is a specification.

The object of my invention is to provide a closure for bottles, jars, and the like, that will be of simple construction and convenient to apply.

My invention consists in the details of construction and arrangement hereinafter more fully described and claimed.

In the drawings: Figure 1 is a side elevation of the closure; Fig. 2 is a front elevation of the same; Fig. 3 is a plan view of the same; Fig. at is a plan view of the cap illustrating how the clip is applied thereto; Fig. 5 is a detailed side elevation of the cap; Fig. 6 is a detailed front elevation of the same; Fig. 7 is a perspective view of the closure illustrating how the cap with its clip is applied to the neck of the container.

The container is represented in the drawing by its neck A only. This container and its cap B may be of any of the usual materials, and this form of closure is especially desirable where fragile materials are used, on account of the fact that breakage and chipping 0f the fragile edges of the neck and cap are avoided.

The neck A of the container has a swelling C forming a shoulder thereon, by means of which a pair of wire clips D may engage with said neck. The cap or cover B of the container, as shown, has four recesses 2 into which the hooks 3 of the two wire clips D engage. Extending downward from these hooks 3 are members 3, and these members are joined by a transverse member 3", which extends under the shoulder or offset formed by the swelling of the neck A. This transverse member 3 has a loop 4; midway between the downwardly extending member 3, which loop extends out from under the shoulder where the transverse part is engaged thereunder, so that a suitable instrument may be inserted to pry the clip into and out of its engaging position. As will be noted, this transverse member 3 is arched upwardly so that it avoids contact with the edges of the shoulder, but makes a two-point bearing with the shoulder at the sides of the loop 4-. Likewise, the hooks 3 extend at a downward angle into the rethe elasticity of the clip.

cesses 2 in the cap B so that contact with the I edges of the cap is avoided, with the advantages hereinbefore referred to.

The entire clip is resilient, and its springiness not only allows it to and disengaged from the container, but allows it to compensate for slight variations in the dimensions of the container and cap, as is necessary in practice.

In order that the clip D may be conveniently mounted as a fixture on the cap B, this cap is provided with lugs E, one of these lugs being adjacent to each recess 2, and formed on the convex outside surface or periphery of the cap. As herein shown, the formation of the clip D is such that the members 3 in each clip converge somewhat as they extend down to the transverse memher 3''. This formation is preferred, since it reduces the size of the clip somewhat without impairing its efficiency. The exact angle at which these members 3 extend downward is immaterial, but, for cooperating with the clips D, the lugs E have their surfaces adjacent to the members 3 of the clip inclined away from the members downwardly to such a degree as to allow a limited swinging movement of the clip outwardly from the container, the clip pivoting with its hooks 3 in the recesses 2.

Relatively to the clip, the lateral extension of the lugs E is only such that the clip will be prevented from being disengaged horizontally from the cap under the ordinary pressure exerted in applying the cap to the neck, but, as will be understood and as is clearly shown in Fig. l, the clip may have its members 3 spread apart so that they slide over the sides of the lugs E when applying the clip to the cap, as allowed by of the adjacent part of the lug E to the member 3 of the clip, as before stated, allows a limited movement of the clip, but this movement, preferably, is not enough to allow the clips to slip over the swelling on the neck of the container without springing apart somewhat, so they hug the swelling 0 of the neck A closely when being pressed down onto the container, and are prevented from rising with respect to the cap and displacing their hooks 3 from the recesses 2. lVhile the lugs E thus limit the swinging of the clips away from each other, the adjacent bulging of the convex surface of the periphery of the cap adjacent each member 3' The inclination be easily applied may "be automaticall of the clip limit the swinging of the clips toward each other, so that they are held practically in position for ready application of the cap, with the clips, to the neck of the container. With this provision, the engagement of the transverse part 8 of the clip v effected, if pressure is applied to the capB, so as'to compress the gasket G, between the cap and neck, enough to bring said transverse part 8 down so low that the hugging pressure of the clip overcomes the resistance at the shoulder.

The convenience of such an arrangement for rapid closing of the containers, such as bottles and jars, is apparent, and it Will also be seen that the cap with its lugs for'the purpose described, is of very simple formation and not diflicult to produce, which is an essential requirement in such an article.

Having fully described my invention,

what I claim as new and desire to secure by Letters Patent is:

Ina closure for containers, a neck, and a Copies of this patent may be obtained for five cents each, by aridressing the Washington, D. 0.

cap having a convex outer surface or periphery, and a substantially fiat upper surface with upwardly open recesses therein adjacent to the periphery, and a clip having hooks engaging in the upwardly open recesses and having members extending down and embracing a segmental partof the cap, and lugs on the cap having surfaces adjacent to the downwardly extending meme bers'of the clip that are inclined away from said members from saidrecesses downward, so that the members have a limited swinging movement, with their hooks acting pivotally in said recesses.

In testimony whereof I have signed my name to this application in the presence of two subscribing witnesses, thise3rd day of January, 1911.
